This has been on my to-do list for sometime.
Until now the host controller (specifically ehci-exynos) is responsible
for enabling VBUS supply. This opens up one more issue which is, when

Adding support to enable/disable VBUS controlled by a regulator
on USB 2.0 port.
This is a part of moving vbus setting out of ehci-exynos.
Since vbus can be handled by USB 2.0 phy itself, so the host

Moreover, setting VBUS in USB 2.0 phy helps both ehci as well
as ohci. This

Use the irq_chip bus_sync_unlock method to update hardware registers
instead of scheduling work from the mask/unmask methods. This simplifies
a bit the driver and make it more uniform with the other GPIO IRQ
drivers.

Without suspend/resume functionality in the USB driver the USB core
will disconnect and reconnect the DLN2 port and because the GPIO
framework does not yet support removal of an in-use controller a
suspend/resume operation will result in a crash.
This patch provides suspend and resume functions fo
As noticed during suspend/resume operations, the IRQ can be unmasked
then disabled in suspend and eventually enabled in resume, but without
being unmasked.
The current implementation does not take into account interactions
between mask/unmask and enable/disable interrupts, and thus in the

First patch in the series fixes a GPIO IRQ issues found during

it is in use.

This patch adds support to load a custom ACPI table that describes
devices connected via the DLN2 USB to I2C/SPI/GPIO bridge.
The ACPI table is loaded at runtime as firmware with the name
dln2.aml, it looks for an ACPI device entry with _HID set to
"DLN2" and makes it the ACPI companion for DL
since the split of host+gadget mode in commit 74c2e9360058 ("usb: musb:
factor out hcd initalization") we leak the usb_hcd struct. We call now
musb_host_cleanup() which does basically usb_remove_hcd() and also sets
the hcd variable to NULL. Doing so makes the finall call to

The Apricorn SATA dongle will occasionally return "USBSUSBSUSB" in
response to SCSI commands when running in UAS mode. Therefore,
disable UAS mode on this dongle.
